Instruments and Meters

Overview of Measured and Metered Values

7.5.1
7SR5 devices have numerous measured and metered values. The measurands are recorded from the analogue
inputs.
Further measurands are calculated from these measured values where the instrument or meter requires meas-
urands from more than 1 input. For example, the electric power is calculated from the voltage and current
measurands.
Instruments and meters can be viewed without entering a password or user ID.
The device functionality is dependent on the analogue input configuration (current and voltage inputs).
Please refer to the Device manual of the 7SR5 device for detailed information and setting instructions.
The user can read measured and metered values on the device display or with Reydisp Manager 2.

Reading Instrument Values from the Device Fascia, HMI screen

7.5.2
You can read measured and metered values on the device display.
For the display, the measured values of a device are summed up in the following groups:
•
Operational measured values
•
Fundamental and symmetrical components
•
Function-specific measured values
•
Minimum values, maximum values, average values
•
Energy metered values
The device instrumentation and metering provides real-time measured quantities and data. This is displayed
on the relay fascia LCD from Main Menu > Instruments.
The instruments are grouped to topic and can be viewed using the arrow buttons, Right arrow → to enter a
group and Up ↑ and Down ↓ arrows to scroll through the instruments.
